Given: f(x)=x^(2)-3 and g(x)=x+1 the composite function g*f is
Ivenika [448]

Answer:

<h2>x³ + x² - 3x - 3</h2>

Step-by-step explanation:

I'm assuming g*f means g times f,  so you want to multiply the two functions together.  

(x² - 3)(x + 1)                 Since the product is 2 binomials, use FOIL

                      =  x²(x) + x²(1) - 3(x) - 3(1)

which simplifies to

<h2>x³ + x² - 3x - 3</h2>

NEED HELP ASAP solve for x : 3/5 = x-1/8 <br>a.5 b.29/5 c.23/5 d.19/5
Levart [38]

Answer:

<h3>\boxed{ \sf{ \bold{ \huge{ \boxed{ \frac{29}{5} }}}}}</h3>

Option B is the correct option.

Step-by-step explanation:

\sf{ \frac{3}{5}  =  \frac{x - 1}{8} }

Apply cross product property

⇒\sf{ 5(x - 1) = 3 \times 8}

Distribute 5 through the parentheses

⇒\sf{5x - 5 = 3 \times 8}

Multiply the numbers

⇒\sf{5x - 5 = 24}

Move 5 to right hand side and change it's sign

⇒\sf{5x = 24 + 5}

Add the numbers

⇒\sf{5x = 29}

Divide both sides of the equation by 5

⇒\sf{ \frac{5x}{5}  =  \frac{29}{5} }

⇒\sf{x =  \frac{29}{5} }

Hope I helped!

Best regards!!
